A multi-dimensional processing and display system is used with a sonar tracking system to monitor ocean-going vessels. The system arranges data in a three-dimensional matrix, which is then reformatted into a two-dimensional matrix. The two-dimensional matrix is decomposed into singular vectors and singular values. Certain data elements in the two-dimensional matrix are enhanced or diminished by modifying selected angular values. A history database is maintained by saving certain of the singular vectors, which is concatenated with the two-dimensional matrix. An enhanced two-dimensional matrix is generated by multiplying the two-dimensional concatenated matrix by the modified singular values and the singular vectors. After data enhancement, the two-dimensional enhanced matrix is reformatted back into a three-dimensional matrix. All or portions of the enhanced three-dimensional matrix can then be displayed. |
